Extra Life is an organization of gamers that play for the benefit of the Children's Miracle Network. This encompasses a great deal of facilities and services that help sick children realize greater potential. It's a worthwhile cause that can benefit the children as all proceeds are donated to various causes and hospitals.
Multiplayer Online Battle Arena games are greatly attractive for a few simple reasons. One, it's live competition between two players without the slow momentum of a story-based plot. And two, most of them are free and only require a cash deposit when you want to unlock a certain aspect of the game. They are essentially pure action from the moment you hit "Play."
